Indel rates in 63 GO slim categories. For each GO slim category indel rates were measured in events (insertions+deletions) per 100 kbp in the protein coding regions of all genes assigned to the particular category. The horizontal black line is the average indel rate in all protein coding regions with available GO annotation. We assumed that errors of indel rates are given by , where Ni is the overall number of indels in GO slim category i, and Li is the total length of all protein coding regions assigned to that category. For GO slim categories with Ni = 0 errors were obtained by setting Ni = 1. The category nucleic acid metabolic process combines nucleobase, nucleoside, nucleotide and nucleic acid metabolic processes.
